Coordinate System Transformation for the SCCs. (Redrawn from [14] (a) To align the primary axes of implanted sensors and peripheral vestibular sense organs, a vector-matrix multiplication operation can perform a coordinate system transformation between the implanted sensors and natural organs. (b) When an electrode is placed to stimulate horizontal canal neurons, a portion of posterior canal neurons can be stimulated erroneously. A vector-matrix multipler (VMM) block can precompensate for the effect and eliminate false representations of motion due to current spread.
